摘　　要：由于发动机喷管烧穿导致试验失败,在发动机的研制中占有相当的数量。针对某型发动机喷管烧穿故障,深入分析了故障原因与机理,并据此提出了防止喷管烧穿故障的改进设计方案。通过相关试验验证,证明了改进措施的有效性,为火箭发动机的优化设计提供了有价值的借鉴。Test fault caused by the nozzle＇ s burned-out has are often seen in the development of an engine. Based on the burned-out fault of some rocket engine nozzle, the mechanism of fault is analyses in detail and the improved design scheme of preventing from burned out is put forward. Through related tests, the validity of the measurement is verified, and a valuable reference is given for the optimization design of rocket engine.
